SEAL-LOCK.

SPECIFICATION forming part of Letters Patent No. 724,038, dated March 31, 1903.

Application filed January 12, 1903. Serial No.'138,593. (No model.)

lowing is a specification, reference being hadV therein to the accompanying drawings.

My invention relates to improvements inV seal-locks which are especially adapted for use on freight-cars, but which may be used to advantage iu sealing other conveyances or receptacles.

The object of my invention is to provide a simple, durable, inexpensive, and practical seal-lock that will be eectual in performing the objects for which a seal is required.

The invention consists of the novel construction, arrangement, and combination of parts hereinafter described and claimed and which are illustrated in the accompanying drawings, in which-a Figure 1 is a front elevation of my lock; Fig.` 2,.a top view thereof as it appears when locked, and Fig. 3 a front View of my indexible frangible seal.

Similar figures referto similar parts throughout the several views.

1n Fig. 2 of the drawings my latch-bar 1 is shown as secured to door 14 by means of a staple 13, which passes through an opening 4 in one end of the said latch-bar; but it may be secured in any suitable manner and may be applied to either swinging or sliding doors.

My latch-bar l is provided near its free end with an obliquely-projecting member 2, having shoulders'3 formed thereon to extend under the arms of my bifurcated latch holder or keeper 5. The bifurcated keeper 5 is provid ed with lugs 5f* on the ends of its arms, and

the space between the arms into which theY obliquely-projecting member 2 is adapted to pass has slanting walls. The shoulders on the member 2 limit the upward movement of the latch-bar 1, and the lugs 5ad prevent the outward movement of the latch-bar 1 when it is down. Each lug 5a is provided with a vertical slot or recess 7, which is adapted to receive the inflexible frangible seal 10 or similar element suitable for the purposes required. WhatI mean by an inflexible frangible seal is a seal that cannot be bent without breaking. The seal 10is so formed as to enable it to be passed down with facility into the said slots 7 and it is provided with oppositely-disposed recesses 11, which enable it to be held and maintained in proper position in said vertical slot 7 by the spring-actuated pins 8, which project into the said slots and enter the oppositely-disposed recesses 11 in the seal 10. The pins 8 are held normally so as to project from the lugs 5a into the vertical slot 7 bythe vspring 9, which are concealed in the interior of the said lugs 5a. The seal 10 is so shaped at the portions 14 that when it is passed down into the vertical slot 7 it pushes the pins 8 in until the recesses 11 register with said pins 8, when the spring 9 forces the pins 8 out again into said recesses 11, and the seal 10 is then held in position in the lugs 5, from which it can be removed only by being broken. The seal 10 when so held by the pins 8 lies in the path of the outward movement of the obliquely-projecting member 2 and the latchbar l, and the latch-bar 1 can be released from the keeper 5 only by breaking the seal 10. The seal 10 may be numbered or other wise marked to prevent the substitution there= for of another seal.

The extended shank 6 of the keeper 5 may be secured to the body l5 in any suitable manner, so as to allow suli'icient space for the latch-bar torest upon the keeper behind the lugs 5a, its member 2 passing between and under the arms of the keeper and behind the seal.

With this description of my invention, what I claim is- In a seal-lock, a bifurcated keeper, proj vided, on its arms, with upturned lugs having oppositely-located slots, and spring-controlled means, projecting into said slots, in combination with an inflexible, frangible seal, formed to slide into said slots and to be held therein by said spring-controlled means, and a latch-bar, provided near its free end with an obliquely-projecting member registering with and adapted to enter the opening between the arms of the keeper when the latch is raised to pass over and behind the lugs, and having shoulders extending under the arms of the keeper, substantially as set forth.

YIn testimony whereof I affix my signature in presence of two witnesses;

JAMES PELLINGTON. Witnesses: V
